Electric start that works always. Never kick the bike. Bike doesn't overheat even on the slowest no air flow trails. Alot of lug and chug power which makes good traction. Suspension is very comfortable because it soaks up all trail trash effectively.

I've only had this bike for a short time but I will say that it seems pretty well built with a good suspension. It handles well on the road and off road. The KTM 450 RFS motor is strong under normal operation.

I told my wife I was buying a bike with everything I wanted on it when it's new, so I ordered this on Beta's BYOB at $12,000 total, in July '14 and received it Sept '14, a great deal for what's in the bike, I was surprised she was good with that. The bike has been reliable and has me riding faster than ever.

This bike is the best combination of a hyper-compliant ride, smooth and easy handling, and relatively agressive power I have even experienced.
The Sachs suspension requires a complete rework to be anything special, but it is now on par with KYB SSS.
BYOB COMPONENTS added.

Absolutely love this bike! Ranged from super tight New England single track on hot days to wide open South Jersey Hammer Run type trails! Unsurpassed reliability, just changed sprockets, chain, rear rotor, both pads, and one linkage bearing at 1850 miles! Valves point on from the factory, but have always been neurotic about air filter servicing. Can't say one negative thing about this bike, and have tested its limits thus far!
Gave it a make over with fresh plastics, and graphics also.

I love this thing! It has gotten better with miles & a little fine tuning. The motor is so much fun & easy to ride. This last ride 12/30/17 had very long patches of solid ice that we were not expecting. I had much less problems with my low seat height, smooth engine and MotoZ Mountain Hybrid tire.

I just purchased this bike used in Dec 2017. When I got the bike it had a head leak either from overheating or the crappy OEM O-rings or a combination of the two. Either way I just replaced the piston with a ProX and added a Slavens S3 head. Because of the weather I havent had a chance to do any dirt riding yet but I'm anxiously awaiting the opportunity. I have a 2016 Yamaha WR450 which is a great bike and almost boringly reliable but its a bit heavy and can be a bear to handle in technical areas so that is where I'm hoping the 300RR will do better. I bought the 300RR with the idea that I'd have it and the WR450 during the 2018 riding season and then I'll decide which one to keep or possibly sell both and go with something different.

It has a very neutral chassis, turns very well but doesn't give much up in stability. The power is very linear and easy to use. If you wan't a hard-hitting 2 stroke, this isn't your bike. Even with the aggressive map switch and the powervalve adjuster turned in, it much more mellow than my Yz. Although the power may not be exciting, it's perfect for gnarly technical terrain. Stock forks were harsh on square-edge obstacles. The Pressure springs(small spring in the top of the fork) are known to be to stiff for most offroad riding. I had them changed out when the forks were revalved. E-start works flawlessly and starts the bike within a couple seconds when cold. Ergo's feel good to me...at 6'1", I was worried that it would feel to small to me, but that's not the case. The rear brake lever is a little low for most people, but I actually prefer it that way and it's adjustable anyway. Brakes themselves feel good, the front in particular is very strong. I don't feel they give up much to the Brembo's on the Ktm's.

40 hour update: replaced the stock rear tire within 20 hours and did the front at about the 35 hour point. I now have a tubliss front and rear, with a new rim in the front because of bad crash I had. In that crash, I also smashed the pipe, split a radiator hose, twisted both radiators, and popped the preload adjusters out of both forks. Beta fixed the forks free of charge, so no complaints there. Separate from that crash, the stock map switch is busted and I blew the fuse for the e-starter, although it blew in extremely wet conditions. The most likely culprit is the horn, it's a pretty common issue that's easy to fix. Also, the stock plastic is extremely brittle and easy to crack.

The broad, torquey power-curve and (relatively) low seat height made this a great successor to the trusty old KDX. I do wish it had a bit wider gearing. I can almost do the same things in 3rd as I can in 1st. It's also a great think to not worry about pre-mixing gas. I'm a forgetful procrastinator with some long stretches between time to ride. I no longer have to look at the full Jerry can in the shop and wonder: "did I mix this when I filled it last month?"
